I hate Joe Stack. Very few people can create sympathy for the IRS, but this guy managed exactly that. Not only did he kill himself and someone else, he also abandoned his family and destroyed their home.
Morality aside, violence against the federal government is stupid. Usually the results are the same: the perpetrator gets killed and everyone else moves on.
If your goal is the abolition of the federal government, then the safest way to go about it is to advocate as many spending programs as possible. The idea would be to produce as much debt as possible, as quickly as possible, so that individuals, foreign governments, and corporations lose confidence in US Treasury bonds.
Like a loving spouse, as much as I criticize the government, I would miss it if it were gone. It's why I nag it about losing weight all the time.
